I used this to marinade beef for shishkabob. It had a good taste but it wasn't near as spicy as It thought it would be. And I used hot mustard, not regular. The only thing different I did was to double the recipe, but doubled it exactly. It was good, like I said, but needs to be kicked up some way, I think.
This marinade was wonderful. I used it on flanken cut beef ribs that were extra thick. They came out tender and flavorful.
This was excellent. I was already prepared for the fact it would not be sinus-clearing so I wasn't disappointed. I used it on rabbit (not sure if that's allowed in Japanese culture, but it's what I had) and it was very flavorful and tender.
